Glow plug problem

I have a 1993 F-350, 7.3 and my problem is that when the ignition switch is turned on, every once in a while the glow plugs don't come on. Can't seem to find out why. What could be the problem? What should be checked first? Since this happens periodicly I don't know what to look for. Please help, Thanks, Tom.

you will bet better answers to this question down in the pre powerstroke 6.9-7.3 diesel forums.

but it sounds to me like you may have a bad ground on the glow plug controller.
